3. He has his own board game: Trump The Game

The Monopoly knock-off bombed when it came out in the late 1980s (despite a cameo from Phil Hartman in a commercial for the game). Trump The Game received a reboot after his “Apprentice” success, but still isn’t a family game night staple.

Trump could’ve owned Tom Brady, instead of merely being friends with him. But the real estate mogul decided the team was a bad investment. Robert Kraft bought the Pats for $172 million. Now the team is worth $2.6 billion and has Super Bowl rings to boot.

He won the Razzie for worst supporting actor in 1989 for the debacle “Ghosts Can’t Do It.” A YouTube clip of the movie describes a scene like this: “Bo Derek faces Donald Trump in a business meeting, with the help of her invisible (to everyone but her) ghost husband, Anthony Quinn.” Yikes.

12. Trump won a presidential primary in California in 2000

As a member of the eccentric Reform Party, Trump appeared on the primary ballot in The Golden State. Trump had withdrawn from the race before the California primary, but still managed to receive 15,311 votes — enough to beat party frontrunner Pat Buchanan in the ballot. Trump also won Michigan.

After Donald cheated on Ivana Trump with actress Marla Maples, the two met in Aspen where Maples asked, “Are you in love with your husband? Because I am.” Ivana also has accused Trump of making her feel "violated" after sex. Trump, 69, married current wife Melania Knauss, 45, in 2005.
